mod_http_oauth2: Implement stateless dynamic client registration
Replaces previous explicit registration that required either the
additional module mod_adhoc_oauth2_client or manually editing the
database. That method was enough to have something to test with, but
would not probably not scale easily.
Dynamic client registration allows creating clients on the fly, which
may be even easier in theory.
In order to not allow basically unauthenticated writes to the database,
we implement a stateless model here.
per_host_key := HMAC(config -> oauth2_registration_key, hostname)
client_id := JWT { client metadata } signed with per_host_key
client_secret := HMAC(per_host_key, client_id)
This should ensure everything we need to know is part of the client_id,
allowing redirects etc to be validated, and the client_secret can be
validated with only the client_id and the per_host_key.
A nonce injected into the client_id JWT should ensure nobody can submit
the same client metadata and retrieve the same client_secret

--- labels: summary: 'HTTP access to prosody’s storage mechanism' ... Introduction ------------ This module gives HTTP access to prosody’s storage mechanism. It uses normal HTTP verbs and [Basic HTTP authentication](http://tools.ietf.org/html/rfc2617), so you could call it RESTful if you like buzzwords. Syntax ------ To Fetch data, issue a normal GET request GET /data[/<host>/<user>]/<store>[/<format>] HTTP/1.1 Authorization: <base64(authzid:password)> OR PUT|POST /data[/<host>/<user>]/<store> HTTP/1.1 Content-Type: text/x-lua | application/json <data> These map to `datamanager.method(user, host, store, data)`, where choice of `method` and its parameters are explained below. ### Verbs Verb Meaning datamanager method -------- ------------------------------- --------------------------- `GET` Just fetch data `load()` or `list_load()` `PUT` Replace all data in the store `store()` `POST` Append item to the store `list_append()` Note: In a `GET` request, if `load()` returns `nil`, `list_load()` will be tried instead. ### Fields Field Description Default ---------- ----------------------------------------------------------------------------------------------------------------------- --------------------------------------------------------------------------- `host` Which virtual host to access Required. If not set in the path, the domain-part of the authzid is used. `user` Which users storage to access Required. If not set in the path, uses the node part of the authzid. `store` Which storage to access. Required. `format` Which format to serialize to. `json` and `lua` are supported. When uploading data, the `Content-Type` header is used. `json` `data` The actual data to upload in a `PUT` or `POST` request. `nil` Note: Only admins can change data for users other than themselves. ### Example usage Here follows some example usage using `curl`. Get your account details: curl http://prosody.local:5280/data/accounts -u user@example.com:secr1t {"password":"secr1t"} Set someones account details: curl -X PUT http://prosody.local:5280/data/example.com/user/accounts -u admin@host:r00tp4ssw0rd --header 'Content-Type: application/json' --data-binary '{"password":"changeme"}' ### Client library - https://metacpan.org/module/Prosody::Mod::Data::Access ### TODO - Use `Accept` header. Compatibility ============= ------- -------------- trunk Doesn't work (uses is_admin) 0.12 Works? ------- --------------
